PLANTER.

Application f1ed September 12, 1925. Serial No. 55,945.

My invention relates to i1npro\ 'en'1ents in corn planters, and has for its principal.. object, to provide anv improved machine for planting corn, and more particularly laiiir corn, and one in which the seed may be planted uniformly and without danger of cracking or grinding the seed, and in which the seed plate is interchangeablewith other seed plates for planting different kinds of l" seed such as cotton.

' More especially my invention consist-s in an improved construction of seed plate and bearing means therefor, which afford tighter joints than heretofore provided between moving parts, so as to eliminate danger of cracking, crushing or grinding` the kaliir corn seed, which is Isomewhat smaller than ordinary corn or cotton seed, and Atherefore requires special apparatus for the proper handling thereof. A further specific object is to provide means-whereby my improved planting mechanism may be substituted for the ordinary corn or cotton planting mechanism wit-hout disturbing the other l parts of the planting device.

These and other features and' objects of my invention will be more clearly under-- stood by having reference to the accompanying drawings, in which I have illustrated one embodiment of my invention.

In the drawings Figure 1 is a top plan view of a seed can base with my improved mechanism attached f thereto. n

Figure 2 is a sectional view of a seed can taken on line 2--2 of Figure 1.

Figure 3 is a bottom view of the can.

Figure 4 is afdetail view in perspective showing the bottom of the base `plate forming a part of my attachment.

Figure 5 is a detail section taken on line 5 5 of Figure 1.

Referring to details of the embodiment of the invention illustrated in the drawings, a seed can is carried by a base ring 11 which Ais pivotally mounted at one side to the main frame 12 by means of a hinge connect-ion 18. When the can is in upright position, it may be held in place by a wing nut 14 on bolt 14a carried on the frame and engaging in a slot 15 in the base ring 11. Mounted in connection with thev frame 12 4is a spout 17 through which the seed is dropped for planting.

la .the fOral shawn. herein? my invention Cells.

stood, however, that this picker-wheel is not used in connection with the mechanism forming the subject matter of the present 1nvvention, but is in position to be utilized in connection with 1 the ordinary or Standard form of` seed plate, with which myspecial lalfir cornmechanism is interchangeable.

Referring now to details of my improved planting mechanism, I provide a spider 25, having an outer annular portion'26, fitting in the bottom of the base ring 11 and detachably securedtherein by suitable means such as hinged lugs 27, 27 `(see Figure 3).

A central cap portion 28 of the spider 25' is spaced radially from the annular portion 26 to form arcuate openings 28a, 28a, the latter being spanned by curved arch members 29, 29, and a segmental web 30 adjacent the delivery spout 17 and carrying the ejector mechanism, details of which will hereinafter be described.

Rotatably mounted below the cap member 28, is the seed plate 35. The latteris provided with a center bearing 36, engaging a stud 37 depending from the cap 28, and having spokes 38 extending to the seed ring 39 of said plate, wherein is provided a plurality of spaced holes 40 formingthe seed As will be seen in Figure 2, the outer periphery of the seed ring 89 closely fits against the annular portion. 26 of the spider while the inner portion of said ring has an ujiinf'ardlycurved portion 41 adjacent the margin of the cap member'28, to form a downwardly inclined continuation of the dome-shaped upper surface of the latter.

Theseed plate 35 is provided with a discharge spout 49, and is secured in closely fitting engagement with the spider 25, as shown, by a base plate 45, extending beneath the seed ring 39 and detachably connected to the annulaiportion 26 of said spider by wing-nuts 46 threaded on bolts 47 and engaging in notches 48 on the edge of said base plate so as to be removable by partial relative rotation of the parts. In the form shown. ,each pair of registering bolts 47 and `rance oi the ejector-` notches 48 are spaeeel at irregular intervals about the late 41) so as to assure `the proper positioning ot said plate, with its seed spout '-ltlbeneath the ejeotor mechanism.

The ejeetiiigl` vri'ieel'iani'sin is inoriiited in a housingl a5 lfoi'iiiin'g partof the connecting web Ill) between the cap member 28 and an-y nular ring` portion 26. Details of this meehzinisni are shown in .Figaro 3,in 'efhieli it Will be seen that a finger 46 is pivotally mounted with-an ejector pin 47 in :position to engage in eaeli suceeesive seed nella() as the seed plate is rotated. Said inger is held under compression of spring 4:8". Cutro-lf means are provided :for limiting the passage vof Seeds in. the cells before they are ejected, siieli njieans herein shown comprising a `.inger 5U having a` be've'lled surface 51 and under preseiire et spring 52 so as `to engage the ripper si .ze oit the eeed ring 39 just in ad- Tlie arrangement is such that the cells v10 are .of the proper size to accommodate one seed, and the passage orf seeds on the surface of the plate restrained or out oil by the finger 50.

`The power for driving the seed plate is derived 'from suitable variable speed driving' mechanism oi usual type, connected to `theplate a gea-r6() mounted on the frame la beneath the can and having arms 61, 61 adapted te rengage lugs 6:2, `6&2, projecting doivn'wardlj7 from the under surface of ,the seed plate wr n the boundaries of the base plate 45, as clearly @bor-vn in lli-paire This arrangement permits the seed can to be tipped on its hinged connection 13 When desired, j j

Among the advantages of the device above described is the provision oi. means` for atliordingr close-litting joints `between the moving .parts ol. the mechanism, r-,oinn'iensnrate with simplicity Vof Construction and ease o` asseinlli'ling and.y disassen'ibling ,the parts.

l claim: 1.- ln a planter, a seed Can, a seed. plate ,at the bottoni ot said can provided With a series of seed nella, a cap member covering the central portieri of said seed plate and having' close fitting engagement with the latol smid cells, a cap member e()veri/iig;l the oen'- trai portion olf said seed plate and havingr close fitting engagement with the latter adjacent said `sec-zd cells, a ring siii-rounding said eeedpl ,l and rigidly connected with said cao i'iieinbei', a base jilateliavi'ng means ailiordi e; detachableengagement with the bottoni of sai-d ring beneath said seed platev at three or more spaced pointsl to hold the latter in close fitting engagement, and means for ejieoting seed from said seed plate.
